may concern:

Be it known that we, ABRAHAM Krrniss, a citizen of the United States, and aresident of the city of New York, in the county of Kings and State of New York, and MAX PAUL NEUMANJ, a citizen of the United States, and a resident of the city of New York, in the county of Queens and State of New York, have invented a certain new and useful Machine for Making Bobbinsfor Electric Batteries, of which the following. is a specification.

This invention relates to a machine for shaping carbon to special forms, known as bobbins, which are used in electric batteries.

The object is to provide means'whereby,

' the bobbins may be produced by means of automatic mechanism in such a manner that they will be uniformly well made.

The invention consists of a cylindrical compressing chamber; means for moving a sticko fspreviously pressed carbon to rest therein; means for forcing a measured quantity of graphite into said chamber and around said carbon stick; and means whereby the graphite thus pressed to conform to the shape of the chamber and having a portion of the carbon stick protruding. beyond-the pressed graphite, will be forced out of the compressing chamber and finally .zontal section approximately delivered' to an inclined receiving chute down which the bobbins thus formed may roll.

In the accompanying drawing: Figure 1 is a front elevation of the machine. Fig. 2 is a sectional elevation, showing the means for moving the previously pressed carbon stick ina difiierent position from that shown in Fig. 1. Fig. 3 is a plan'view of the machine.

isatransverse section on the line X-X of Fig. 1, showing the position of parts when the pressed graphite and carbon stick are forced out of the compressing chamber.

The main frame 1 of the machine is provided with bearings 2 in which a driving shaft 3 is journaled. Secured to shaft 3 is a earn 4.- having a groove 5 in which a roller 6 travels. Roller 6 is journaled on a bar 7, one end ofwhich is slotted so that it can ride on the shaft 3. The other end of bar 7 connected to an arm 8 secured to a shaft.

, 9 which is journaled in suitable bearings on the main frame. Secured to shaft 9 is a gear segment 10 rack 11 forming part of a slide 12having vertical movement in guides 18. -ltiounted in vertical slots 14: formed in slide 12 is a shaft 15 to which a lever 16 is secured. Springs 17 mounted in the slide and bearing against collars 18 loosely mounted on shaft 15 cause the shaft to be normally held in the upper ends of the slots. Lever 16 is held against a stationary pin 19 by means of a spring 20. Forming part of lever 16 is a plunger arm 21 having a recess 22 formed in its outer end. When the slide 12 occupies the down position shown in Fig. 1, action of pin 19 on lever 16 causes arm. 21 oi'the lever to stand horizontal.

Secured to shaft 91 is a cam 23 which acts upon an arm of a lever 24 which is pivoted at 25, the leverbcing held against the cam by means of a spring 26. The other arm of lever 2 1 is connected by a link 27 to a slide 28 having reciprocating" movement in horizontal guides. Forming part of slide 28 is a plunger 29 which serves to more the lowermost of a series of previously pressed carbon sticks 30 from a passage 31 forming part of a magazine 32. As shown in Fig. 1, one end of this carbon stick is moved into the recess 22 of plunger arm 21. 1

By means of part a of cam groove a rocking movement is imparted to shaft 9 of slide 12, spring 20 acting on lever 16 (arises swinging movement of the lever,

which is in mesh with a 10 5 thereby causing the plupger arm 21 to move,

, which is formed in a horizontal bed 36,

the carbon stick 30 seated in recess 22 up ward, an opening 33 being" formed in pa -,sage 31. to permit this moven nanh W hen swinging movement of lever 16 causes plun ger 21 to be moved to rest against a'stop 34, the plunger arm and carbon stick 30, v ill be standing vertical, and as upward move; ment of the slide continues, the carbon stick and a portion of the plunger arm will be moved up into a cylindrical chamber 35.

r reference to Fig; 2 it will be seen that the carbon stick is smaller in diameter than. the chamber 35 and extends nearly to the upper end thereof, while the plunger arm 21 is equal to the diameter of the chamber and extends a short distance into the lower end thereof.

Resting on the horizontal bed 36 is a turntable 37 having a shaft 38 which is freeto rotate in a bearing 39. Turn-table 37 is provided with a series of cylindrical receptacles 40, which are open. to and bottom. Located above the turnta 1e 37 is a stationary hopper 41 having; an opening 42 through its bottom, which opening is arranged to register with one oi? the receptacles d0, so that powdered graphite that may be placed in the hopperwill flow into the receptacle. To the lower end of shaft 38 is secured a ratchet wheel as having teeth equal in number to the receptacles i0 that are formed in the turn-table 37. Adapted .for engagement with the teeth of ratchet wheel 4:3 is a spring pressed pawl l4: pivoted upon one arm of a bell-crank lever 45, which is'pivoted at 46. By means of a spring d7, the bell-crank lever is held against an ad ustable stop as. On the other arm oi the bellcrank lever is journaled a-roller 49, against whichan incline on slide 12 bears when theslide nears the end or its upward movement, thereby causing the bell-crank lever to be actuated, whereby movement is impartedeto the turn-table 37 SllfilGlfilli] to move another receptacle 4:0 to register with opening 42 of the hopper ii. Successive movements of the turn-table 37 cause one of the receptacles 40, that is filled with powdered graphite. t be moved to rest in range with the cvlin real chamber 35 in which the plunger art 1 served to place a previously pressed carbon stick 50,

Located above the turn-table 3'? and in range with the chamber 35 and the filled receptacle 40 above it, is a plunger 51 which has reciprocating movementin vertical '52. Plunger 51 is provided in mesh with a gear segment which is secured to a rock-shaft 55 journaled in suit" able bearings on the main frame, Secured to rock-shait 55 is an arm whic" nected to one end of a bar 57, the o of the bar being slotted so it W71. on she-it 3 Journaled on 5'4" is re a rash 52% downwardly extending;

to the position shown in Fig.

7 a lever 6 which is 58 which travels in a cam groove 5% in cam wheel 60 which is secured to the strait 3;

After part a of cam groove 5 has caused the slide 12 and turn-table 37 to be moved 8, and while 6 causes the slide to remain stationary, part c of camgroove 59, by action on roller 58, bar 5'1 arm 56, rock-shaft 55 merit 5e and rack 53 of plunger 51 will cause downward movement of the plunger. Plunger 51 has the same diameter as the receptacle ii), the chamber 35 and the plunger arm 21, so that as the plunger moves downward, the powdered graphite willthereby be forced irom the receptacle 40 into the chamber 35,

' around the carbon stick 30 and against the upper end of the plunger arm 21. The graphite will accordingly be compressed to conform to the cylindrical shapen chamber 85, and caused to adhere to the carbon stick 30;. Owing to the action of springs 17, plunger arm 21 will serve to compress the portion of the graphitenext to the plunger arm until the degree of compression caused by plunger 53. is suiiicicnt to overcome the force of the springs 1? thereby causing downward movement oiarm 21 until shaft 15 reaches the end oi slots 1%, after which time theplunger arm 911, carbon stick 30 and compressed graphite 61 will be moved to the positionshown in Fig: 9.

- While part 01 of cam groove 59 causes plunger 5h to remain stationary, part c oi to the down position. During" downward movement of the slide 12,: thereon engaginga roller 63 journaled on pivoted at 65, permits movement of the lever. Lever 64: is con nected by a link 66 to a slide 67 hich has reciprocating movement in horizontal guides 68. Forming part of slide 67 is a receptacle 69. By means of a spring 1 0 connected to slide 67, the slide, the linlr 66, lever 6 are moved so that roller 63 on the leve'r is forced against a straight Z1 forming part oi slide 12, as shown in 2. Doing the first part of the downward movement of slide 12, plunger arm will be moved down away from the carbon s"clr and the pressed carbon 61 which will 2*) on be held up by adherence to the wall of compressing chamber During this m-ent of the slide, the straight suri 'Zfi acting on roller' 63 will cause lever (i i: and

slide 6'"! to remain'stationaryi During last part of the downward movement slide 12, action of pin 19 on lever 16 causes plunger armfil to swing to the horizontal roller and position, and action of incline 62 63 causes movement oi the lever 64 6? from the position shown in to position shown in l.

an incline 62,

ger 51 to be moved farther downward, thereby; causing the carbo stick and pressed graphite to be moved (it of the compressing chamber 35' and into the receptacle 69,

forming part of slide 67, as shown in Fig.

'10. Part of cam groove 59 causes plunger 51 to be moved to the up position. Part a of cam groove 5 will then cause slide 12' to be moved to the up position, whereby plunger arm 21 movesanother carbon stick into the compressing chamber, and the slide 67 will move the receptacle 69 to the posi- -tion shown in Figs. 2 and 6, during which movement the carbon stick and pressed.

graphite or bobbin as it maynow be called, will be forced against a 'fixed in'cline 72, whereby the bobbin .willJbe forced through side openings 73 and 74: of the receptacle,

and caused to tumble onto. an inclined chute 7 5, down which the bobbin may roll.

During the successive operations of the 'machine,,in which powdered graphite is fed from magazine 41 to the measuring receptacles 40, the graphite, which must be limited in quantity owing to a tendency to pack, is constantly agitated by means of a series of rods 76 which extend downward from an oscillating disk 77 located above the magazine, Disk 77 is secured to a shaft 7 8 which is free to *rotate in a bearing 79. Disk 77 is provided with segmental gear teeth 80 in mesh with a rack on a bar 81 which has rcciprocating'movement in horizontal guides82. Bar 81 is connected by a link 83 to a lever 84 which is pivoted at 85. Lever 8% is connected by a'link 86 to an arm 87 which is secured to the rock-shaft 55. It

will be understood that movement of the rock-shaft 55 causes oscillating movement of disk 77 .and consequent movement of the agitating rods 76 in the powdered graphite co'ntained' in the magazine 41.

In order to maintain a constant supplypf 'the'necessarily limited quantity of graphite in magazine 41, an auxiliary magazine. 88

is provided. The outlet of this ma'gazine 1S,

controlled by means of a reciprocatingslide 89. Slide 89 isconnected by a-link 90 to v one arm of a lever 91 which is pivoted at 92.

'The other arm of lever 91 is provided with a roller 93 which travels in a heart-shaped cam groove 94 formed in a large gear wheel 95. Gear Wheel 95 is in. mesh with a small gear wheel 96 which is secured to the driving shaft 3. After several operations of the into magazine 11, which has capacity only for the limited quantity of graphite previ ously' referred to.
